A 2013 study assessing the impact of colors on individuals, conducted by Travelodge, has been the focus point of various interpretations and publications. Here are two of them.

According to Suzy Strutner (The Huffington Post), a blue bedroom doesn’t only restore the oasis feeling any bedroom should convey: it is the ONE color your bedroom needs to be to truly affect your mood.

As for Jaymi Mccann (The Daily Mail), who quotes a Sleep Expert from Edinburgh Sleep Center, the color blue stimulates a specific cell receptor in our eye retina, that speaks positively to the brain part controlling sleep, and mood. More data? Below.

‘Your bedroom should be calm. But all too often, it becomes a place of laptop clicks, TV hums and iPhone buzzes. While it will take effort and discipline to treat your bedroom like the oasis it ought to be, you can cut a few corners with one simple trick:

Paint it blue.

The color blue promotes feelings of peace, calm and serenity, and can make a room feel bigger. Shades of blue have also been proven to lower blood pressure. In one 2013 study by Travelodge, people slept longer in a blue bedroom than in bedrooms of other colors.

A room that feels bigger, looks more spacious and helps us get more sleep? We’ll take it.

Katie Reynolds, an Ace Hardware design expert, recommends decorating your bedroom with two or three tones of the same blue color for a look that promotes relaxation.’

‘* Blue is thought to slow the heart rate and even reduce blood pressure

* People sleeping in a blue room get seven hours 52 minutes sleep per night

* Purple rooms can stimulate the brain, making it difficult to nod off

Feeling blue may not be all bad when it comes to enjoying a good night’s sleep. Those with bedrooms this colour tend to get the best rest – nearly eight hours a night – and wake feeling happy and positive. According to a survey, it is linked to calm, soothing feelings and is thought to slow the heart rate and even reduce blood pressure.

However, it’s best to avoid purple, which is too stimulating and can cut nightly hours of rest to less than six.

The study, carried out by Travelodge, looked into 2,000 homes across the country to investigate the influence of colour on quality of sleep.

They found that people sleeping in rooms decorated in calm colours, such as yellow, blue or green, received the best night’s sleep.

Chris Idzikowski, Sleep Expert from the Edinburgh Sleep Centre said: ‘This is an amazing result, as there are specialised receptors called ganglion cells in the retina part of our eyes, which are most sensitive to the colour blue.

‘These receptors feed information into an area deep in our brain that controls 24 hour rhythms, and affects how we perform and feel during the day. That interaction between light, sleep and wakefulness is supremely important.’’
